The 26-year-old joined the Gunners from Villarreal in January 2015 but has struggled to nail down a regular spot in Arsene Wenger's XI, making just 41 Premier League appearances in two-and-a-half seasons.

According to The Sun, Los Che are keen on bringing the Brazilian back to Spain and are prepared to pay around £10m for his services.

Wenger's side acquired Gabriel for more than £11m but are willing to accept a loss on him as they build up funds to bring in big-name signings in the remaining weeks of the summer transfer window.
